5-(4-chloro-benzylidene)-10,11-dihydro-5H-dibenzo[a,d]cycloheptene is a complex organic compound with a molecular formula of C18H15Cl. It is characterized by a dibenzo[a,d]cycloheptene core, which is a seven-membered ring system with two benzene rings fused together. The compound features a 4-chloro-benzylidene group attached to the 5-position of the dibenzo[a,d]cycloheptene, which introduces a chlorine atom at the para position of the benzylidene moiety. This chemical structure is significant in the field of organic chemistry, potentially serving as a precursor or intermediate in the synthesis of various pharmaceuticals, agrochemicals, or other specialty chemicals. The presence of the chlorine atom can influence the reactivity and properties of the molecule, making it a subject of interest for further chemical modifications and applications.
The CAS Registry Mumber 1236-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 6 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1236-65: (6*1)+(5*2)+(4*3)+(3*6)+(2*6)+(1*5)=63 63 % 10 = 3 So 1236-65-3 is a valid CAS Registry Number.
